Great stuff from Danny O'Neil of 710 ESPN Seattle on the history of the strained relationship between Marshawn Lynch and the Seahawks:

You heard of the bird? Well, Lynch flashed it toward the Seattle bench while lining up in the backfield during the middle of the game, leaving us all to sort through just how much ill will was behind the gesture.

Here are the particulars: Thursday night game in Arizona, Seattle has third-and-goal at the Arizona 1, the Seahawks leading 17-13. The Seahawks offense broke the huddle, and before getting set, Lynch turned and flashed a middle finger toward Seattle's sideline.

It was a pass play, and Lynch even wound up throwing a great block on a play that resulted in a touchdown to tight end Kellen Davis.

It's a play that has come to typify Lynch's last two seasons here in Seattle. A player whose effort can't be questioned based on what you see between the whistles, but whose attitude toward his employer can appear outright hostile.
